Adding rules

I am attempting to create a c program that can add rules to the audit sub-system and monitor the resulting events. I have read through the code in libaudit.h, audit.h, audit.c, and auditsc.c as well as several man pages pertaining to audit and extended searching of the web. I am trying to add a rule using audit_add_rule() so audit will "watch" a file. The first problem is that there doesn't seem to be an appropriate field under the "Rule Fields" section of audit.h. The second is that the value must be an integer... I have succeeded in adding the rule from the command-line using auditctl. I would appreciate any help you can offer, Steve I am using: audit-1.2.3-1 and glibc-kernheaders-3.0-37
